Unique fingerprint: What makes the nerve cells unmistakable?


Fingerprints are one of the things that is totally unique for each individual. Let’s say, 1 billion people, there have to be 1 billion unique fingerprints. Even by the wildest chance, there can never be any similarity between the two sets. Such is the characteristics, therefore if there is a test or report based on or fingerprint, there is absolutely no refuting it. But, what makes the fingerprints, so distinguished? What is responsible for such unique characteristics? 

What happens and how

During the development of the fetus, there are only a limited number of genes, which is acquired, from each of the parents. For humans it is, 23 pairs, that is 46 genes. But, the offspring are never the uncanny replica of their parents. Variations are there and therefore the diversity. 

These variations occur, due to many processes that take place, like crossing over, slicing, mutation and many more. Each of these processes gives a unique identity of the developing nerve cells and when all are clubbed together, they form a unique set of neural networks.


Each has an exclusive neural circuit and their specific functions. There is nil error in their working, with the different protein produced, each marks itself distinctly. 

Alternate Slicing, leads to different protein variants, resulting to different neural networks. Each different Neural network gives the unique print, of each individual. This unique print of the complex neural network that is created by alternate splicing of only a limited number of genes, the fingerprint. 

Fingerprints are always exclusive

This fingerprint is always exclusive to each individual and can never resemble others from another being. 

A research team at the University of Basel, are conducting experiments and studying a detailed map of alternative splicing, to understand the creation of the fingerprints. Their research has been published in Nature Neuroscience.
